250ml Shortfills: Are Big Bottle Vape Juices Worth It? (UK 2026)

If you get through a 100ml shortfill every week or two, you've probably wondered whether a bigger bottle would save you money. It usually does. A 250ml shortfill gives you two and a half times the juice of a 100ml for far less than two and a half times the price.

The price per ml, compared

Here's how the sizes compare using our Zombie Blood range, where every flavour comes in all three sizes:

Size	Price	Price per ml
50ml shortfill	£6.99	about 14p
100ml shortfill	£8.99	about 9p
250ml shortfill	£14.99	about 6p

Buying 250ml as two and a half 100ml bottles would cost about £22.48. The single 250ml bottle saves you about £7.50.

Who should buy a 250ml shortfill?

• Regular sub-ohm vapers who get through 100ml or more a week.
• People with one favourite flavour they always come back to.
• Anyone tired of reordering. One bottle lasts most vapers 3 to 5 weeks.

If you like to switch flavours often, smaller bottles or a buy 4 get 2 free mix of 50ml and 100ml shortfills may suit you better.

How to add nicotine to a 250ml shortfill

Like all shortfills, 250ml bottles are sold at 0mg so you can add your own nic shots. As a guide, each 10ml 18mg shot added to 250ml raises the strength by about 0.7mg:

18mg shots added	Total liquid	Final strength
2	270ml	about 1.3mg
3	280ml	about 1.9mg
4	290ml	about 2.5mg

If your bottle doesn't have room for all the shots, pour some juice into a clean empty bottle first and split the shots between them. Our e-liquid calculator works out any strength.

Keeping a big bottle fresh

• Keep the cap tight and store it somewhere cool and dark.
• Decant a week's worth into a smaller bottle, so the big one isn't opened every day.
• Shake it before each refill, especially after adding nicotine.
